SPEQIFCATION forming part of Letters Patent No. 461,452, dated October 20,1891.

" Application filed June 15. 1891. Serial No.396,307. (No model.)

To all whom uma-y concern:

Be itlkn'own that I, GEORGE R. SCRUGHAM, acitzen ofthe United States, and a resident of Lexington, county of Fayette, and State useful Improvements in Electric-Wire Connectors, (Case 1,). ofwhich the following is a specification.'`

My inventionrelates ,to a device for makjoints between 'thel .ends of the conductrailway: system.`

The exact natureof the in vention is set fortliv the'accompanying-drawings,in whiohigure'll, injverticalsection, shows the mechanicalconstrnotion; and Fig. 2,. an elevation. y

The wires tobe joined are letteredE. F represents. two conical; conductors provided .with h'olesin the manner of a tube.

'The conductorsF contain the. wires E, which are riveted at G to prevent their being pulled 'free from the conductors F.

,D is a doubly-conical truncated conductor connecting the-conductors F, so that the conical surfaces of conductor D-coincide, respectively, -Wtithextensions of the conical 4surfaces of the conductorsF. H are axial extensions, which enter the larger ends'of'the conductors F. -These ex-v tensions belong to .the conductor D. One of the extensions has diametrical holes I so located that whenffthe extension is inserted into the conductor F any one of the holes may be opposite and in line with a hole in the conductor Fin suchv a manner that the screw A may be passed through both. A screw A likewise passes through the other conductor- F and extension H.

J are washers or spacers fitting over one of the extensions H.-

, When the connector is applied for the first time, the wires E should be cut to such ay length that several washers J must be placed upon the extension,

, with the conical surface of the conductor D,

" whereby have invented certainnew andv so that the conical sun. face of one'con'ductor -F may be continuous become slack, they may be made taut by removing one-or more of the washers and drawing the conductor F sniiiciently tocome in conconicalor. at the least continuous.'- If there is any nnevenrissgithe same m'ay be reduced j with a file, which will easily remove thecomy paratively soft `metal copper.V `Fig. 1shows about the least-.number (three) of spacers or 'washers emp1oyed,'it being ,supposed that other'spacers have been removed for the -purposeof taking up slack. .flfno spacers were used, the abrnptness of diameter 'from condnctor D to conductor F would be so great as regardscon-t-igmas to make the trolleyjump,slightly,^which would not be a serious objection.

I claim as my invcntion.- 1. A trolley-wire connector' consisting of the combinationof conical conductors fast cned to theends of the trolley-wires, a doubly- ,conical truncated conductor- -between the other-named'conductors, extensions upon the last-named conductor fitting in holes in the first-named'conical conductors, through which pass retaining-screws, and washers or spacers separating the doubly-conical conductor from one of the conical conductors.

2. A trolley-wire connectorcohsistinp; of

the combination of conical conductors F, fast'- ened tothe ends of the,t.iolley-wires, a doublyconical conductor D, fastened to said conical conductors, and detachable washers between j the conductor D and the'cbnductor or conductors F, the diameters of the conductors and washers` being such that t'he'surfaces of the same are continuous.

3. A trolley-wire connector consisting of the combination of two conductors fastened to the ends of thetrolley-wires, a middle con- IOO ductor batting against and fastened to the my nvnton have signed my name,in presrst-named conductors; andmeans for. a.- ence of two witnesses, this 8th, day of June, justing the distance betweeihe said middle 1891. conductor and the Said lst-namedconduct- GEORGE R.

In testimony that I claim the foregoing as C. R. HANSON.
